HDPE/PP Gas Pipe systems with various stiffness classes which are designed for utility and industrial applications. HDPE Profile Pipe has gradually replaced the status of PVC-U Profile Pipe and become the main consumer pipeline.

The plastic (PEHD or PP) is melted in the main extruder:(1) (mostly black material to provide the required UV-resistance of the spiral pipe) and in the co-extruder (2) (mostly yellow material to provide the required bright, inspection friendly inside surface). In the melt distributor (3) the materia
